Level 1 Natural Selection
Question | Answer |
---|---|
The change in a species or population over time | Evolution |
All genes in a population | Gene Pool |
The differential reproductive success of an organism that is best adapted to the environment | Natural Selection |
The percentage of each gene in a population | Gene Frequency |
The mathematical theory that a population is in genetic equilibrium or the gene frequency does not change unless one of the five tenets occur. The null hypothesis is that a population is in genetic equilibrium. | Hardy Weinberg Equilibrium |
the allele frequency of the dominant allele A | p |
the allele frequency of the recessive allele a | q |
The gene frequency for homozygous dominant AA | q2 |
The gene frequency for the homozygous recessive aa | p2 |
The gene frequency for the heterozygous Aa | 2pq |
The frequency of A or a in the population | allele frequency |
A trait | adaptation |
A change in the chromosome, gene, or DNA. Mutations can be silent, deadly, or beneficial. | mutation |
A shift in a small population due to a random event. | Genetic drift |
Mating where selection of mate does not depend on phenotype or genotype. | Random mating |
The movement of genes into or out of a population. | Gene flow |
The ability of an organism to survive and reproduce. | Fitness |
